Objectives To explore the effects of control measures and dynamic prevalence of drinking water endemic fluorosis in China, to provide basis and technique support for endemic fluorosis control in China. Methods The survey was carried out according to the national surveillance Scheme of Endemic Fuorosis. The fulfillment of control measures and the quality of water improving projects were surveyed. Household water sample and urine of children aged 8-12 years were collected and fluoride content was detected by iron selective electrode method. Check the teeth of children aged 8-12 years. Dental fluorosis was diagnosed by Dean's method. Results projects were build in 84 endemic villages in 2006, and the average water improving rate came to 73.98% fluoride contents of half the surveyed spots were over the standard, mainly between 1.0-2.0 mg/L, and the urine controlled just in only few spots and it was in moderate or severe status in some endemic areas for many years. Conclusions Little progress of control measures in drinking water endemic fluorosis counties surveyed has been made in these two years. Projects of running out of status and over standard of water fluorosis are frequently seen. Dental fluorosis in many spots is not controlled.

AIM: To investigate the clinical effect of phacoemulsification and intraocular lens ( IOL ) implantation for cataract patients after corneal refractive surgery, and to compare the accuracy of the different refractive IOL.
METHODS:The data of 120 myopia cases (160 eyes) in our hospital, who underwent cataract surgery and corneal refractive surgery were analyzed. Corneal curvature K value before corneal refractive surgery were obtained and calculated by using history method. Corneal curvature correction numerical method and corneal topography were used to record K value of patients with incomplete data before and after treatment. The K value was substituted into the formula. By comparing the actual cataract surgery and refractive state expected refractive status (-0. 50D), the accuracy of IOL refractive obtained from three methods was compared.
RESULTS: The average best corrected visual acuity before cataract surgery was 0. 25 ± 0. 05, and it was improved ( 0. 80 ± 0. 05 ) after surgery. The average spherical equivalent (SE) was -1. 98±1. 75 before surgery and +0.85±3.38 after surgery (P<0.05). The K values of 48 cases were calculated by clinical history method ( CHM ) and that of 73 cases was calculated with the adjusted keratometry method ( AKM) . The K values of 39 cases were calculated using the corneal topography method ( CTM) .
CONCLUSION: For patients with corneal refractive surgery, the appropriate method can be selected according to clinical symptoms, history, etc. and this may help to accurately calculate IOL. For patients with complete data, CHM can be used to provide corneal K values, while for those with incomplete data, AKM and CHM can be used.

Objective:To study the relationships between age,the state of genital tract and vaginitis,cervical erosion and vulvae leukoplakia in married women.Methods:Gynecologic inspection and laboratory examination were performed in 1 253 patients diagnosed vaginitis,cervicitis and vulvae leukoplakia in a women screen in a certain area in Chongqing in 2007.Statistics analysis was made by SAS8.1.Results:Of 1 253 patiens,45.89% had vaginitis,44.69%,cervical erosion,and 3.35%,vulvae leukoplakia,6.07%,the other conditions.Age,vaginal cleanness degree,candida infection were risk factors of vaginitis;Age,vaginal cleanness degree were related to cervical erosion and vulvae leukoplakia.Conclusion:Vaginitis,cervical erosion and vulvae leukoplakia should arouse more attention in the prevention and treatment of women genital tract disease in the future,and the standard etiology treatment should be performed to get microcosmic ecological balance.The perfect control and monitoring system for gynecologic disease should be established,and service quality of women health care should be improved.

Payment system reforms have become an important part of Chinese healthcare reforms, and global budget has been seen as a major trend. Based on the practice and data of four pilot hospitals in Beijing which have implemented the global budget, this paper focuses on analyzing the effects of implementation on the following aspects and provides references for policy improvements: medical services, average medical cost, total health expenditure, medical cost structure, average length of stay and out-of-pocket expense percentages.

Objective To discuss the factors which are related with curative effects of endoscopic sinus sur-gery of sinusitis and nasal polyps. Methods 480 patients with rhinosinusopatia who were received endoscopic sinus surgery were retrospectively analyzed. Results The curative rate was 74.5% ,improved rate was 18.1% ,ineffective rate was 7.3%,the effective rate was 92.7%. Conclusion ESS is an effective method for the treatment of chronic sinusitis and nasal polyps. However,the therapeutic effects were closely related with the clinical types of lesion. Ap-propriate treatment to the diseased middle turbinate and deviated nasal septum during the period of surgery and effec-tive combined treatment after operation are very importint to the long-term therapeutic effects of ESS on these lesion.

Objective To investigate the effect of TGF ? 1 and TGF ? on hepatic apoptosis in hepatocelluler carcinoma (HCC) after transcather arterial chemoembolization (TACE).Methods The specimens were surgically obtained from 36 patients who had been treated by TACE (TACE group) and 19 patients without any treatments (no TACE group). Expression of TGF ? 1 and TGF ? in HCC tissues was detected by immunohistochemical method. Apoptosis was detected by ISEL method.Results Expression rates of TGF ? 1 in HCC tissues of TACE group and no TACE group were 86.11% and 36.84% respectively.expression rates of TGF ? in HCC tissues of TACE group and on TACE group were 0.0088 and 0.1901 respectively.Conclusions After TACE, the expression of TGF ? 1 was enhanced to accelerate the hepatic apoptosis in HCC.TGF ? was mainly related to the cell proliferation in HCC.That the expression of TGF ? was inhibited after TACE might accelerate the hepatic apoptosis of HCC.

Objective To investigate the expression and clinical signification of tumor M2 pyruvate kinase in pa-tients with CRC, and to try to find a reliable and atraumatic method to predict the progress and pronosis in the CRC. Methods ELISA method was used to determine the serum levels of tM2-PK in 68 patients with CRC,40 pa-tients with colorectal polyps and 40 cases of normal subjects; immunohistochemistry ( IHC ) methods were respec-tively used to detect the expression of tM2-PK in tissues. Results ① The level of serum tM2-PK in patients with CRC was significantly higher than the group of patients with polyps and the normal subjects ( P<0.05 ) . The serum tM2-PK levels was closely correlated to tumor size and Duke stage.②The positive rate of tissue tM2-PK was signif-icantly higher in CRC than in colorectal polyps and normal subjects ( P<0.05 ) . Tissue tM2-PK levels was closely correlated to tumor size,Duke stage and differentiation grade. ③Serum tM2-PK levels was correlated to tissue tM2-PK levels (r=0.357,P=0.003). Conclusion Combined detection of expression of tM2-PK can provide the basis theory for the diagnosis and prognosis evaluation of CRC.

Objective Detected Her-2/neu, matrix metalloproteinases-2 (MMP-2) and Leptin in stomach cancer serum and tissue, discussed their roles in occurance and development of gastric cancer. Methods Detected the ex-pression of Her-2/neu, MMP-2 and Leptin in serum by ELISA, and detected the expression of Her-2/neu, MMP-2 and Leptin in stomach cancer tissue by IHC. Results The positive rates of Her-2/neu, MMP-2, Leptin in gas-tric cancer serum were higher than the positive rates in control group ( P<0.05 ) . The positive rates of Her-2/neu, MMP-2, Leptin in gastric cancer tissues were higher than the positive rates in adjacent tissues (P<0.05 ). The positive expressions of two tests had consistency. In tissues, the positive expression rates of Her-2/neu,MMP-2 and Leptin were correlated with the depth of invasion,lymph node metastasis, clinical stage(P<0.05). Their ex-pression was not correlated with sex, age, size, site of tumor and the degree of differentiation. In serum, the posi-tive expression of Her-2/neu was correlated with the depth of invasion, lymph node metastasis, clinical stage( P<0.05 ) . The positive expression of MMP-2 was correlated with lymph node metastasis ( P<0.05 ) . The positive ex-pression of Leptin had no significant correlation with pathological features. Conclusion Her-2/neu,MMP-2 and Leptin promote the occurrence, development and transfer process of gastric cancer. It can be used for clinical diag-nosis, guide the targeted therapy and provide scientific and reasonable reference for gastric cancer prognosis.
